Survival after myocardial infarction according to left ventricular function and heart failure symptoms.

ABSTRACT:

Aims

Left ventricular (LV) dysfunction following acute myocardial infarction (AMI) is common even in the absence of signs and symptoms of heart failure (HF). Recent trials of patients with LV dysfunction post-AMI have demonstrated low event rates during follow-up. We aimed to assess the real-world prevalence and outcomes post-AMI, stratified by LV ejection fraction (LVEF) and the presence or absence of HF symptoms.

Methods and results

Cohort study of patients with AMI registered in the Norwegian Myocardial Infarction Registry 2013-2022. Outcomes were short- and long-term all-cause mortality. Mortality was assessed by Kaplan-Meier survival curves, Life Table and multivariable Cox regression models.

Results

Among 70 809 AMI patients (mean age 68.1 ± 12.9 years, 31% fema
